SPECIFICATION forming part of Letters Patent No, 351,289, dated October19, 1886.

Application tiled March 29, ISSG. Serial No. 196,996. (No model.)

To @ZZ whom it may concern:

Beit known that l, MAX F. E. S'rAD'riiiUnL- LER, a. citizen of theUnited States, and a resident of Castle Grove, in the county of J onesand State of Iowa, have invented certain new and useful Improvements inVashing Machines; and l do hereby declare that the following is a full,clear, and exact description of the invention, which will enable othersskilled in the art to which it appert-ains to make and use the saine,reference being had to the aecompanying drawings, which form a part ofthis specification, and in which-d Figurc l is a longitudinal verticalsectional view of my improved washingmachine, showing it in conditionfor operation. Fig. 2 is a similar view of the machine, showing the lidraised and the revolving rubber raised and supported above the rockingbottom. Fig. 3 is a perspective view of the rocking bottom, showingportions broken away. Fig. fl isa similar view of the rubber and ilsframe, showing portions broken away. Fig. 5 is a top view of saidmachine.

Similar letters of reference indicate corresponding parts in all thefigures.

My invention has relation to that class of washing-machines in which acorrugated roller is j onrnaled between the ends of arms andreciprocated over a corrugated bottoni, and it consists in the improvedconstruction and coinbination of parts of such a machine, having aroller provided with a number of cross-slats secured in the edges of twoheads and rolled over a bottom composed of similar slats secured to twoside pieces having a bulged central portion, causing the said bottom torock, as hereinafter more fully described and claimed.

In the accompanying drawings, the letter A indicates the suds-boX, whichis suitably mounted upon legs B, and which is provided with metallicstrips C G, secured upon the inner sides of the side pieces near theupper edges, and parallel with the same. The Slat bottom is composed oftwo side pieces, D D, having their lower edges bulged at their centers,and square slatsE are secured with their ends in perforations F in theside pieces parallel with the lower edges of the same, and have theiredges projecting upward, and

spaces between them. The side pieces of the rocking bottom are providedwith laterallyprojectingbolts G G at their middles, and these bolts litinto perforations Hin the lower ends of metallic strips l, secured uponthe inner sides of the side pieces of the suds-loox, near the loweredges and at the middles ofthe same, allowing the bottom tvo-rock uponthese bolts as well as with the hul'ged side pieces upon the bottom ofthe suds-box.

A roller is composed of two circular heads` J J, having their centerscountersunk from the outer faces, and connected at their centers bymeans of a shaft, K, inserted through the centers of the heads, andsecured by means of nuts M upon the ends ofthe rod or shaft ltting inthe countersinks N ofthe heads. The inner faces .of the heads are formedwith triangular shoulders O, and the ends of square strips P fit intothese shoulders, the ends being cut away at the portions which tit intothe shoulders, forming shoulders Q, resting upon the edges ol" theheads, and the strips are secured to the heads by means of nails orscrews R, inserted through the heads into the cutaway portions of thestrips.

The ends of the shaft are smooth and project beyond the screw-threadedportions which have the nuts, and these smooth ends are journaled in thelower ends of arms S S, the upper ends of which are bifurcatedandconnected by means of cross-pieces T T, secured to the upper bifurcatedends of the arms. A bar, U, is secured at` its inner end to thecrossbars, and has its outer end pivoted to a lever, V, near the upperend of the same, the lower end ofthe lever being pivoted in the end of aslid ing bar, NV. This bar slides under the bottom of the suds-box in anotch, X, in the crosspiece at that end of the bottom and in a bulgemade in a metallic strip, Y, secured to the under side of thecross-piece, and the sliding bar is provided at its inner end with adownwardly-projecting pin, Z, which stops the bar from sliding out toofar, and at its middle the sliding bar has a perforation, A, which mayregister with a perforation, B, in the notch of the cross-bar, throughwhich perforations a bolt, C', or pin may be inserted, holding thesliding bar at its desired distance out.

The cover D of the suds-box consists of two IOO longitudinal bars, Ef,the ends of which rest in notches F in the ends of the suds-box, and theend of the cover nearest to the operating-lever is provided with a wideboard, G, to which a 5 bolt, H, is pivoted by means of a staple, Il',which bolt may support the outer cross-piece of the rubber,whichcross-piece is formed with with a recess, J', in its under side, intowhich the end of the bolt may t, lifting the rubber 1o up from therocking bottom, and keeping it at that end of the suds-box, as shown inFig.

2. A lid, K', is pivoted at its end at theinner edge of the wide boardtothe side piece, E', and at the free end of the said cover is a narrowboard, L', and a downwardly and outwardly inclined board, M', whichleaves space upon the upper edge of that end piece of the suds-boxl tosecure a clothes-wringer upon it. The longitudinal bars of the cover aresecured 2o in their notches at a sufficient distance from the sidepieces of the suds-box to allow the bifurcated arms of the rubber toslide between the longitudinal metallic strips upon the side pieces andthe longitudinal bars of the lid. It will be seen that as the rubber isreciprocated or rolled over the rocking bottom the bottom will bedepressed at the end at which the roller is, and in this mannertheroller will depress the bottom and the clothes upon the same into thewater, while the otherend of the bottom will be above water, causing thewater to rush through the clothes, and thus cleanse them, and at thesame time throwing the clothes upon the bottom with sufiicient forceupward from the bottom, in its upward motion, that other surfaces'willbe exposed.

When the machine is not used, the sliding bar having the lever pivotedto its outer end is slid in under the machine, so as to be outof the loway, and when it is to be used the bar is drawn out until theperforations in the bar andin the notch of the cross-piece correspond,when the pin or bolt is inserted, holding the bar rigid.

Having thus described my invention, I claim and desire to secure byLetters'Patent of the United Statesl. In a washingmachine, thecombination of two rubber-heads having countersunk centers, and havingtriangular shoulders upon their inner sides, square strips having their5o shown and set forth.

2. In a washing-machine, the combination 6o of a suds-box having across-piece at one end of its bottom provided with a notch in its upperedge having a perforation in the notch, a bulged strip of metal securedto the under side of the bottom of the suds-box, a rubber having anoutwardly-proj ectingbar, abar sliding in the bulged strip and in thenotch,l and having a perforation registering with the perforation in thenotch, a pin for the perforations, and an operating-lever pivoted in theouter 7o end of the sliding bar, and having the outer end of the bar ofthe rubber pivoted near itsv upper end, as and for the purpose shown andset forth.

3. In a washing-machine, the combination of a sudsbox having twometallic strips secured to the inner sides of the side pieces near theupper edges and having a rocking slat bottom, a lid having twolongitudinal bars resting with its ends in notches in the end piecesofthe suds-box and havinga pivoted cover,and a rubber having aSlat-roller journaled in the ends of arms sliding between thelongitudinal bars of the lid and the strips of the side pieces of thesuds-boX, and connected by cross-pieces 8 5 having means forreciprocating it, as and for the purpose shown and set forth.

In testimony that I claim the foregoing as my own I have hereunto aixedmy signature in presence of two witnesses.
